What is better as mutex on Cortex-M4 - Bitband or LDREX/STREX

Amir

The two options are available.

What is the difference in respect of "cost" "speed" and "complexity" for the two method?

When we need more than few mutexs like that, say 100, is the answer different?

    Hi amiry,

    ok, thank you. I understood your method. It seems to be performed successfully. However the number of read and write times will be bigger than LDREX/STREX method. As Joseph Yiu said, the benefit of the bitband method would be small.

    Best regards,
